BRUCE BOB/LAND, OF CHIGAGQIILLINOIS.

To @ZZ 'whom t may concern Ie it known that I, BRUCE BoRLANn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Locks, of which the followingl is a specification, reference being had therein to the accompanying drawing.

My invention relates to locks, and especially to locks adapted to be used as safedeposit locks, and the main object is to provide a system in which a series of locks set to differentcombinations are operated by a common intermediary, preferably in the nature of a compound key, between the locks and operator, other objects being also apparent from the disclosure.

My invention consists in the organiza-- tions, arrangement, and combinations of parts hereinafter described and pointed out in the claims.

In carrying out my invention I employ a series of locks, each preferably set for a different key, and an intermediary preferably in the nature of a compound key adapted to be temporarily assembled with each of said locks and to receive the respective key or keys for operating the said locks.

' n practice the locks are preferably all of the same construction, and so a detailed description of the organization and mode of operation of one will answer for all.

The loc comprises a casing 30 provided with a cap or cover 31 held thereon by suitable screws engaging lugs 32, the whole being secured to a door 33 by suitable screws 3 4, as shown in Fig. 2, passing through screw-holes 35 into the door. ,The bolt 36 is provided with a shoulder or oHset 37 inside the casing from which the upper and lower bolt-tails 38 and 39 extend. The boltgears 40 and 41 mesh with each other and with rack-teeth on the tails; the gear 40 is motmted on a stub 42 on the cap 31 as shown in Fig. 2, and the gear 41 is mounted in a cup 43 on the case. The cup 43 is cut away and flattened to allow the bolt-tails to move, and the bolt-tails are cut away to clear the lugs 32, as shown in Fig. 4. I employ Ya plurality of two-part tumblers to control the bolt, and in the present embodiment of the invention these tumblers consist of co-acting pivoted members in the form of intermeshing spur-gears; I have shown two tumblers for convenience of illustration, it being of course understood that any suitable number may be employed. The gears 44 and 45 constituting the main or gate parts of these tumblers are mounted upon a hub 46 carried in the casing in a manner hereinafter described, and the gears 47 and 48 constituting the supplemental parts of the tumblers l are mounted in the cup 43, the arrangement being such thatthe parts 44 and 47 coperate and the parts 45 and 48 coperate as shown in Figs. 10, 11, 16 and 17, it being understood lthat Figs. 10 and 11 are separated sectional views showing these tumblers and associated parts and that Figs. 16 and 17 show these tumblers lifted out ot' the case of Fig. 18 in which the parts are superimposed one upon the other, as shown in Figs. 2 and 4. An additional gear 49 is located in the cup 43 behind the gear 48 for a purpose hereinafter described. The parts of these tumblers may of course be set in a variety of positions with respect to each other, and the main parts 44 and 45 are provided with gatings 50 for the recept-ion of the fence 51 on thebolt 36, so that when the tumblers are moved to aline their gatings in the path of the fence, the bolt may be retractedA by turning the bolt-gears 40 and 41, it being of course understood that the tumblers normally stand with their gatings variously out of the path of the fence, as shown in Fig. 4 for example.

The gears 47 and 48 are provided with blank spaces as shown in Figs. 16 and 17,

and when the parts are assembled in locked position these blanks are alined and are in contact with the teeth of the gears 44 and 45 so that they cannot be turned farther to the right. If either of the gears be displaced, as by any person attempting to pick the lock, it can be returned to normal position by merely rotating it to the right untilits Y blank comes into contact with the teeth of safe-deposit box for example, and is adapted to be operated by an intermediary in the nature of a compound key which is tempo rarily assembled with it on the front of its door and which receives the operating key or keys. For this purpose each lock is provided with a sleeve 52 on its cap which extends through the door (Figs. 1 and 2), and is concentric with the axial line of the parts 41, 47 and 48 and adapted to receive that part of the intermediary which operates the lock as shown in Fig. 2. The intermediary may be o-f any form suitable for the purpose intended, and in the present embodiment consists of a compound key which comprises a case 53 and a cap 54, connected by suitable screw-bolts (not shown). A shaft 55 is with a collar 57 fixed thereto, which is irregular in contour or shape, being hexagonal in the form shown in the drawings, the openings in the parts 41,47, 48, and 52 being of corresponding size and shape to allow this collar to pass therethrough to seat in a corresponding opening in the gear 49 when the compound key is employed, as shown in Figs. 2, 12 and 18. The shaft is provided near its front end with a gear 58 lying against the cap 54. Between t-he collar 57 and the gear 58 a plurality of concentric sleevesV 59, 60 and 61 are mounted upon the shaft one within the other, as shown in Figs. 1 and 2, one for each tumbler and the bolt-gears of the lock.

Each sleeve is provided on its rear end with a collar 62, 63 and 64, respectively, corresponding in size and shape with collar 57, and forming therewith a battery of collars adapted to be alined to pass into and out of the lock and to be reciprocated to operate the latter. As shown at 65, 66, 67 and 68 in Fig. 1, the openings in the parts 41, 47 48 and 49 respectively correspond in shape and size with the collars, and when the gatings 50 are in locked position (Fig. 4) these irregular openings register in axial direction to receive the alined battery of collars, the arrangement being such that the collar 57 seats in the opening 68 ofthe gear 49, as shown in Figs. 12 and 18, the collar 62 in the opening 67 of the gear 48 as shown in Figs. 11 and 17, the collar 63 in the opening 66 of the gear 47 as-shown in Figs. 10 and 16, and the collar 64 in the'opening 65 of the gear 41, as shown in Figs. 9 and 15, the assemblage being represented in its entirety in Fig. 2. Y

The sleeves 60 and 61 which operate the tumblers of the lock by their collars are operatedby tumblers in the compound key and which in the present embodiment consist of pivoted spur-geared spring-pressed levers and circular parts consisting of gears fixed to the ends of the sleeves opposite the collars. As shown in Figs. 1, 2, 6 and 7,

, the inner sleeve 61 has a gear 69 next to the gear 5S, and the next sleeve 60 has a gear next to and of the same size and character as the gear 69. Each of the circular parts 69 and 70 is operated by a pair of levers, one of which is operated by the customers or depositors key and the other by the guards key. As shown in Figs. 6 and 7 the guards levers or tumblers 71 and 72 are pivoted at 73 in one end of the case 53, being spring-pressed by the springs 74 as shown and are adapted to be turned on their pivots by the operation of the guards key 7 5 which enters a key-hole in a key-hub 7 6, which is provided with a semi-circular disk 77 co-acting with a stop 78 in the case to restrict the movement ot the guards key to a halt-turn, as shown in Figs. 3 and 8. The levers 71 and 72 are provided at their free ends with segmental racks to coperate with the gears 69 and 70 respectively, to rotate the sleeves 60 and 6l and operate the collars 62 and 63 which when the compound key is in place in the lock coperate with the correspondingly shaped openings 66 and 67 of the parts 47 and 48 of the tumblers of the lock to move the tumblers to unguarded position, as shown in Figs. 10 and 11. The gnard7s key-hub normally stands in the position shown in Fig. 3, and when the guards key is given' a 'half turn to the position of Figs. 5, 6, and 7, its bittings will operate the tumblers 71 and 72 to move them to the positions shown in these last two figures; rlhe customers levers or tumblers 79 and 80 are pivoted at 81 in the opposite end ot' the case, being springpressed by springs 82 and adapted to be turned on their pivots by the operation of the customers key 83 which enters a keyhole in the key-hub 84, which normally stands in the position shown in Figs. 5 to 8. The customers key-hub 84 has a flat face 85 as shown in Figs. 6, 7 and 14, and is provided with an intermittent gear S6 resting against the rear wall of the case and adapted to engage with a gear 87 on the sleeve 59 to communicate motion to the collar 64 and its associated bolt-gear 41 with which the collar interlocks, as shown in Figs. 2 and 15, when the compound key is in the lock. The gear 87 is located between the rear wall of the case 53 and the gear 70, and is somewhat larger than the latter.

The tumblers 79 and 8() normally rest upon the flat tace 85 of the customer-s keyhub, as shown in Figs. 3, 6 and 7, with their .teeth out of engagement with the teeth oi the parts 69 and 70, and the guards tuinblers 71 and 72 normally rest with their teeth in engagement with the parts 69 and 70, as shown in Fig. 3. In this position the teeth of the parts 69 and 70 are out of engagement with the teeth of the customers tumblers 79 and 80, as shown in Figs. 6 and 7. `When the guards key is given a half turn from the normal position oi Fig. 3 to the position of Figs. 5 to 7 to unguard the lock, as shown in Figs. 6 and 7, the teeth of the parts 69 and 70 pass by the teeth on the customers tumblers 79 and S0, and when the customers key is turned from the normal position of Figs. 1 and 5 to 8 to the position indicated by the character a in Fig. 1 the tnmblers 79 and 80 are raised by the cam-action of the hub into mesh with the teeth of the gears 69 and 70, it being understood that these movements oi the hubs 76 and 84 are successive and that the hub 84 by its cam action on the tumblers locks the tnmblers 69 and 70 in their unguarded position. Further rotation of the cnstomers key to the position indicated by the character y in Fig. 1 cams the tumblers 79 and 8O as shown in Fig. 14, and further `rotates the gears 69 and 70, which by their associated collars 62 and 63 rotate the twopart tumblers oi the lock to aline their gatings 50 in the path of the `tence 51.

The intermittent gear 86 normally occupies a position with its teeth out of engagement with the teeth ot the gear 87 as shown in Fig. 3, and the rotation of the customers key-hub S4 to the position y also brings the first tooth of the gear 86 into engagement with the teeth of the gear 87 (Fig. 14), and continued rotation oft the key-hub in the Idirection of the arrows in Figs. 1 and S turns the sleeve 59 and its collar 64 to move the bolt-gears 41 and 40 to retract the bolt.

The continued rotation of the gears 69 and 70 from the position to the y position by the cnstomers tuinblers moves the guards tumblers to t-he position shown in Fig. 14, and the gears 69 and 70 are provided with cams S8 and 89 respectively which then stand in the return paths ot the tumbler-s 71 and 72 and prevent them trom snapping back under t-he inHuence of their springs 74. The cams 88 and 89 are so placed as to be beyond the extreme position to which the guards key can raise the tumblers 7l and 72, so that if the combined action ot the gnards and customers keys should move either of the gears 69 and 70 fart-her than the eXtreme position to which the guards key alone could move them the tumblers are not moved tart-her as the cams merely slide over them. The cams are cut away at 90 and 91 (Figs. 6 and 7) so as to give clearance to the tumblers 79 and 8O and when these tumblers are brought into mesh with 69 and 70 they will not strike the cams. Vhen the tumblers 7 9 and S0 mesh with 69 and 70, at the a' position, the guard may withdraw his key, and so be free to serve other customers while the first customer is completing the unlocking of his boX. It the customer desires to temporarily lock his door, as while his inner box is out, he may relock by turning his key back to the a: position to shoot and lock Athe bolt, although it is still unguarded. By this means he can dispense with the guards service in returning his box and unlocking his door, but as the customers tumblers are against the hub but not down on the flat-face 85 and are in mesh with gears 69 and 70 leaving their collars out of register the compound-key cannot be withdrawn. The door may then be locked by the customer again turning to the as position, and before the guard can remove the compound-key he must turn the customers hub (by any tool or the linger) to its normal position of Fig. 1, so that the flatface 85 allows the tumblers 79 and 80 to drop out of engagement with the parts 69 and 70 by the action of the springs 82 (Figs. 6 and 7), and as the guards key is also out the springs 74 turn the parts of the tumblers to their original positions to aline their collars 62 and 63 with the other collars so the compound-key may be withdrawn. The lock is then guarded and locked. Il the guard turned the customers key-hub away from normal he could turn it only to the y position as the gear 86 would then mesh with the gear 87 which is held from turning by the dis-alinenient of the gatings of the lock tumblers. In relooking the customer may also turn back to original position of Fig. 1, whereby the flat-face 85 of his keyhub allows the tumblers 79 and 80 to drop to the position of Fig. 3, and the springs 74 will then throw the tumblers back to normal position, thereby rotating the parts t-o aline their collars with the other collars, thus both locking and guarding the lock, and the compound-key may then be removed. j

The lock may be reset to coperate with different combinations of the collars controlled by the bittings of different keys, and this resetting operation is controlled by a supplemental or inanagers lock which in the present instance consists of an ordinary pin-tumbler lock 92. The hub of this lock is provided with a gear 93 meshing with the gear 58 upon the end of the shaft 55, so that rotation of the hub of the managers lock rotates the collar 57 of the shaft 55 of the compound key. W'hen the compound key is in position in the lock the shaft 55 is in its seat 56 and the collar 57 is seated in the correspondingly shaped opening 68 of the gear 49, as shown in Figs. 2, 12 and 18, so that rotation of the shaft rotates the gear 49 of' the lock.

A gear 94 is journaled on trunnions 95 in the case of the lock and meshes with the gear 49, the cup 43 being cut away for this pur- 'pose (Fig. 12). The ronttrunnion is provided with an arm 96, and the upper bolttail 38 is provided with a projection or stop 97 which lies in the path of the arm when the bolt is shot (Fig. 18) and prevents the gear 94 from turning to the lett or contraclockwise. The front trunnion is also provided with a cam 98, which is under the arm and is adapted to coperate with a latch 99 pivoted upon a post 100 in the case 30 to ncrmally 'maintain its :tree end out of engagement with a lug 101 projecting laterally from the rear face of the bolt-tail 38. The rear trunnion of the gear 94 is provided with an intermittent gear 102, the tooth of which meshes with a depression 103 in the arm 104 of a bell crank lever pivoted at 105 on the case 30, and whose other arm 106 carries the post 46 (Fig. 12) upon which the circularl parts 44 and 45 of the -tumblers are pivoted.

In order to reset the tumblers of the lock to coperate with a new combination or arrangement of the collars of the compoundkey corresponding with bittings of a different key, such as the customers key 107, the guards and rst customers keys 75 and 83 unlock and retract the bolt in the manner heretofore described, at which time the parts in the lock take the position shown in Fig. 19, with the projection 97 withdrawn Jfrom the path of the arm 96. The managers key 108a is then inserted in the lock 92 and is turned contraclockwise a. third of a revolution until the arm 96 strikes a lower project-ion or sto-p 108 on the bolt-tail 38, as shown in Fig. 20, this movement of the managers lock also moving the cam 98 outv of engagement with the latch 99, to allo-w the latter to drop upon the 4backwardly projecting lug 101, as shown in Fig. 20. The bolt is now shot and locked bylthe latch 99 engaging the depression in lug 101, the parts then standing as shown in Fig. 21, leaving the managers lock unlocked by reason of the stop 108 being projected out of t-he path of the arm 96, and leaving the keys in thev unlocked position of Fig. 14. The managers key is now further turned contraclockwise, the projection 108 being out of the path of the arm 96 to permit this movement, which brings the tooth of the intermittent gear 102 around to mesh with the depression 103 of the arm 104 of the bell crank lever (Fig. 22), and further movement of the managers key moves the bellcrank on its pivotand thereby throws parts 44 and 45 out of engagement with the parts 47 and 48, as shown in Fig. 22, leaving the parts of the tumblers disconnected'and in position to be reset with relation to each other upon the bittings of `a different keyA 107. The customers and guards keys'- 75 and 83 are now removed, although in this instance the guards key need notbe removed as the 11e-setting is now upon a new to the bittings of the guards key and the new eustomers key, and the gears 47 and 48 are correspondingly operated to assume? a dii'erent relation with respect to the gears 44 and 45. This operation brings the gears 47 and 48 into their unlocked position, at? which time the bolt-gears begin to operatei on the bolt-tails 4which are arrested by the l projection 101 striking the latch 99. The` managers key is now reversed or moved cessity provided with a guards portion in .clockwise and causes the gear 102 to -reverse the movement of the bell-crank and thus throw the gears 44 and 45 back 4into engage-ment with the gears 47 and 48 upon the new setting or combination, and theV turth er turning of the managers key brings the cam 98 into engagement with the latch .99 and raises the latter and brings the arm 96 up against the projection 97 which prevents further movement of the managers key, the parts then being in the position shown in Fig. 23. The latch 99 being thus raised out of the path of the bolt the customer can now retract the bolt to the position. shown in Fig. 24, and the continued turning of the managers lock in Clockwise i direction until the key is in its withdrawal position brings the parts of the lock back to the position of Fig. 19, with the tumblers set for the bittings of the new key. The views shown in Figs. 19 to 24 are made with the parts 40, 41, 44, 47 and 48 lifted out in order to show the other parts to better advantage, the part .45 being partially cut away. l/Vhile this description of re-setting the lock is made with respect to a new customers key, it is obvious that the same may be re-set upon a new guards key, or upon a new guards key and a new customers key, or upon a new customers key alone.

While 1 have shown the compound key as operated by keys it is obvious that the same results may be obtained by making the gears 69 and 70 in the form of dials adapted to be hand operated, in which case the gear S7 would be turned by hand. The managers lock would preferably remain the same.

In Fig. 29 1 have shown a series of sate-l all are operated by the intermediary. The

locks are as shown upon the rear wall of the doors, one of the bo-Xes being open in this ligure to illustrate this fact, and the intermediary is assembled to coperate with the locks when the doors are closed by inserting the shaft and collars into the lock sleeve, projections 109 on the face of the door taking into suitable openings in the ease of the intermediary to steady the latter in position. The intermediary is a compound key in that it comprises a plurality of parts to operate the locks such as a part to operate the `bolt of the lock and a part to operate the tumbler or tumblers of the lock, and also a part, such as the managers lock, to control the re-setting operation in cases where the locks are adapted to be re-set' for different keys.

Safe-deposit locks as now usually constructed have multiple key locks, one key for each depositor and a common key for the guard, and 4each lock therefore is of neto be reset or 4each must have within it the 95 means (such as a latch or a supplemental managers lock) to control this resetting; by my invention in its more extended application I obviate the necessity of removing Athe locks in the one case and eliminate the managers lo-cks with latches from all the locks in the other case, and unite this supplemental lock for all the locks in a single device. It is obvious ,that the elimination ot'A all these lguards portions from the locks reduces the essential parts to a` mimimum while retaining all Vthe advantages of the multiple key-locks, and similarly the elimination of all the managers locks or the latches reduces the parts to a minimum while retaining all the advantages of controlling the resetting for different keys by a third party, as the manager. The intermediary is a unitary structure for the guards portions of a series of multiple keylocks instead of multiplying these guards portions ythroughout all the locks; and also in its more extended use as described is a unitary structure `for the managers locks controlling a series of locks in resetting for dilterent keys instead of multiplying these managers `locks throughout all the locks.

By this invention the lock cannot be left unguarded as `the intermediary cannot be removed until `the lock is guarded, and as the guard retains custody of the intermediary it follows that the unguarded condition existing while the intermediary is in the lock is made apparent by the presence of the intermediary in the lock.
